DSTACKED is a utility for customizing your DOOM savegames. With this
program you can tailor the amount "goodies" a player possesses. You can
give a player any weapons, any number of rounds (up to 65,535), armor, keys,
light amplification goggles, berserk, map, radiation suit, invulnerability,
and "ghost" attributes. Weapons, rounds and invulnerability last for all
levels afterward; all other goodies have the duration of a single level.
So who cares if the nightmare setting is unfair; get stacked and kick butt!
